Definitions

  • the present invention generally relates to a lubricating apparatus for automatically lubricating a chain by being driven thereby and, more particularly, to a checker-arm chain lubricating apparatus suitable for a small-size chain and a high-speed chain having a construction in which a lubricating pump is operated by a checker arm oscillated by the operation of the chain.
  • An apparatus is known as a connveyor chain lubricating apparatus, in which motion of a checker arm oscillated by a traveling chain is transmitted to a plunger of a reciprocating pump unit through a cam for automatic lubrication of the chain.
  • FIG. 9 shows an example of a conventional chain lubricating apparatus as mentioned above.
  • a lubricating apparatus A1 has a frame A3 fixed at a predetermined position in the vicinity of a travel path of a conveyor chain A2.
  • a checker arm A4 and a cam shaft A6 fixed with a cam A5 are swingably supported on the frame A3.
  • the checker arm A4 is rotatively arranged at the tip end thereof with a checker roller A8 that abuts against a roller A7 of the chain A2.
  • the checker arm A4 is arranged such that the roller A7 pushes the checker roller A8 as the chain A2 moves to oscillate forward, thereby allowing the roller A7 to pass.
  • Restoration torque is given by a return spring, not shown, installed on the cam shaft A6 such that, when the checker roller detaches from the roller A7, the checker arm returns again to the position indicated in the above-mentioned figure.
  • a roller follower A10 linked with a plunger of a reciprocating pump unit A9 is pressed by a spring A11 against a cam face formed around the cam A5.
  • a lubricant is taken into the pump unit A9 from a lubricant tank (not shown) which is linked to the inlet port of the pump unit A9 and the lubricant is discharged from the tip of a lubricant nozzle A12 which is linked to the discharge port of the pump unit A9 toward the chain A2 when the checker arm moves to return.
  • the lubricating apparatus using the conventional checker arm having the above-mentioned construction has been developed for lubricating conveyor chains that are relatively large in size and slow in operating speed.
  • the roller follower linked to the plunger of the pump unit is made to follow the profile of the circumferential face of the cam, so that the oscillation angle of the checker arm becomes as large as about 38 degrees, thereby making it hard to operate the plunger at high speeds.
  • This drawback makes a lubricating apparatus of this type unsuitable for a small-size chain having a small pitch between rollers and bushings or for a chain operated at high speeds.
  • the lubricating apparatus is required to have an additional mechanism by which a clutch is installed between cam and cam shaft and the checker arm is rotated to a retired position by rotating an operator knob arranged on the cam shaft and a stopper mechanism by which the checker arm is held at the retired position. This increases the number of parts used in the apparatus, making the construction complicated and thus, increasing the manufacturing cost.
  • a checker-arm chain lubricating apparatus which includes: a main body case fixedly placed in a vicinity of a travel path of a chain; a cam shaft swingably supported on the main body case, wherein the cam shaft has an axis intersecting a direction in which the chain travels, the cam shaft having a protruding portion protruding outside the main body case; a checker arm fixed at a base end thereof on the protruding portion, wherein a tip end of the checker arm is engaged with the chain as the chain travels so that the checker arm is oscillated from an engagement start position to a disengagement position; a return spring for returning the checker arm to the engagement start position when the tip end of the checker arm is disengaged from the chain at the disengagement position; a plunger activating cam fixed to the cam shaft, wherein the plunger activating cam is formed at a position eccentric from a center of the cam shaft toward a radial outside thereof, and the plunge
  • the checker-arm is composed of an arm main body fixed to the cam shaft and a ducking arm swingably supported at a base end thereof on a tip end of the arm main body and having a checker roller at a tip end of the ducking arm, the checker roller being engaged with the chain, the ducking arm being swingable only in a direction opposite the direction the chain normally travels from an extended position in a direction extending to the tip end of the arm main body and, simultaneously, being held at the extended position by a force of a spring to oscillate against the force of the spring when the chain travels in a direction opposite to the direction the chain normally travels to clear an engagement between the chain and the checker roller.
  • a cam shaft hole is formed in the base end of the checker-arm for allowing the cam shaft to be inserted through the same shaft hole and an index pin having tip end which can go in and out of the cam shaft hole and which can be operated from outside the checker arm and a spring for forcing the index pin in a protruding direction, the cam shaft being formed on a circumferential surface thereof with a plurality of index holes in which the tip end of each index pin of the plurality of the index pins is selectively inserted for positioningly fixing the checker-arm.
  • the plurality of index holes are formed on the cam shaft along any of a radial direction thereof and an axial direction thereof.
  • the cam face of the plunger activating cam which is fixed to the cam shaft together with the checker arm, recedes and then the cam follower moves by following the movement of the cam face along with the plunger of the pump unit.
  • the plunger moves in the direction in which the lubricant is taken into the pump unit, thereby supplying the lubricant stored in the lubricant tank, which communicates with the inlet port of the pump unit, into the pump unit.
  • the lubricant is discharged from the discharge port of the pump unit into the lubricating nozzle through which the lubricant is jetted to the chain at a high speed.
  • the checker arm is composed of the arm main body fixed on the cam shaft and the ducking arm swingably supported at the base end thereof on the tip end of the arm main body and having a checker roller at the tip end of the ducking arm, the checker roller being adapted to engage with the chain, the arm main body and the ducking arm oscillate in an integrated manner around the cam shaft to perform the above-mentioned lubricating operation when the chain moves in the normal travel direction.
  • the cam shaft is inserted in the cam shaft hole formed at the base end side of the checker arm, and the tip of the index pin, arranged on the checker arm, is inserted selectively in one of the index holes formed at a plurality of positions on the circumference of the cam shaft to fix the checker arm to the cam shaft, only inserting the index pin can easily fix the checker arm to the cam shaft or easily change checker arm positions as required.
  • index holes are formed at a plurality of positions along the circumferential direction of the cam shaft, lubrication of any chains that travel at a variety of angles with the mounting attitude of the lubricating apparatus kept horizontal can be accomplished. If the index holes are formed at a plurality of positions along the axial direction of the cam shaft, selecting one of the index holes into which the index pin can be inserted, may optimize the engagement position of the checker arm in the width direction of the chain corresponding to the size of the chain to fix the checker arm to the cam shaft.

  • the ducking arm 9B can oscillate from a position extended from the tip end of the arm main body 9D indicated by solid line shown in FIG. 6 to the direction reverse to the normal travel direction of the chain 2 indicated by an imaginary line shown in the same figure around the pivot pin 9C.
  • the swinging movement from the extended position forward is blocked by a movement blocking plate 9E that abuts the front end face of the ducking arm 9B at the extended position.
  • the arm main body 9D is prevented from oscillating in the reverse direction by the abutting of the stopper face 11B of the plunger activating cam 11 of FIG. 5 fixed to the cam shaft 10 against the stopper 13, so that, when the checker roller 9A is pushed by the roller R of the chain 2, only the ducking arm 9B swings against the force of the compression spring 9G clockwise around the pivot pin 9C, thereby letting the roller R pass.
  • the force of the compression spring 9G returns the ducking arm 9B to the extended position via the spring plunger 9F.
  • the oscillation angle of the ducking arm 9B is large due to a high reverse travel speed of the chain 2 or a large amount of interference between the roller R and the checker roller 9A, the lower end face of the spring plunger 9F moves over the base end upper face of the ducking arm 9B to the end face side in the rear, thereby holding the ducking arm 9B by the force of the compression spring 9G in the lateral attitude relative to the reverse travel direction of the chain 2.
  • the above-mentioned novel constitution reduces the wear of the pivot pin 9C and the spring plunger 9F due to the oscillation of the ducking arm 9B in the reverse travel of the chain 2. It should be noted that if the ducking arm 9B is left lateral in attitude, the ducking arm 9B may be manually returned to the extended position after the reverse travel of the chain 2.

  • the above-mentioned hole 9I allows the cam shaft hole 9J to communicate with the outer surface of the base end portion of the arm main body 9D, an internal thread being formed in the vicinity of the opening of the outer surface of the base end portion.
  • a spring holding plug 9K formed at the center thereof with a hole through which the index pin 9H goes, is mated with the internal thread.
  • the spring holding plug 9K holds a compression spring 9L which presses the tip of the index pin 9H into the hole 9I.
  • the index pin is provided with an operator knob 9M. Manually pulling the operator knob 9M can take the tip of the index pin 9H out of the index hole 10A, 10B provided in the cam shaft 10.
  • index holes 10A and 10B are arranged at positions 90 degrees apart from each other in the radial direction in one cross section and at right angles to the axis of the cam shaft 10 as shown in FIG. 7. At the same time, as shown in FIGS. 2 and 3, these index holes are formed equidistantly along the axis of the cam shaft 10.
  • FIG. 8 is a diagram illustrating a state in which the tip of the index pin 9H has been inserted in the index hole 10B and the checker arm 9 is laterally fixed as compared to the position shown in FIG. 7.
  • the checker arm 9 is held in the position shown in FIG. 7 to prevent the checker roller 9A from interfering with the roller of the chain 2.
  • the checker arm 9 When the checker arm 9 is installed in the position shown in FIG. 8, the chain that is traveling down in the vertical direction, although not shown, can be lubricated. In this case, the position of the lubricating apparatus 1 may be held without change, so that there is no need to separately provide a bleeder or similar which are required when the pump unit 4 is rotated by 90 degrees.
  • the index pin 9H can be moved to the optimum index hole 10A or 10B arranged along the axis of the cam shaft 10.
  • the number of index holes and the positions of the index holes formed in the cam shaft may be selected appropriately to apply the lubricating apparatus to a chain that is driven in the diagonal direction.
  • the checker arm is composed of the arm main body and the ducking arm provided with the checker roller. It will be apparent that, if the chain is driven only in one direction and therefore cannot be driven in the reverse direction, the checker arm may be a single-unit part.
  • the above-mentioned embodiment is applicable to not only a roller chain, but also a bushed chain.
  • the checker roller may be omitted and the tip of the checker arm may be directly engaged with the roller of the chain.
  • the checker arm having the ducking arm may be used and, at the same time, a pair of lubricating apparatuses 1, set to the opposite chain drive directions, respectively, may be used.
  • the ducking arm is surely returned to the extended position, if the swivel angle of the ducking arm at reverse travel is large, when the chain travels forward after traveling backward, by either optimizing the shape of the contact portion between the lower end face of the spring plunger 9F and the upper face of the base end of the ducking arm shown in FIG. 7 or a torsion coil spring is loaded around the pivot pin 9C instead of the compression spring 9G.
  • the plunger activating cam causes the plunger of the pump unit 4 to discharge lubricant via the cam follower.
  • the cam follower may be integrated with the plunger and the cam face of the plunger activating cam may be directly abutted against the lower end of the plunger.
  • the lubricant can be jetted from the lubricating nozzle to the chain so fast that the lubricant is applied to the chain in the form of mist, resulting in efficient chain lubrication with a small amount of lubricant. Consequently, the lubricating apparatus according to the invention can reduce lubricant consumption.
  • the construction in which only the ducking arm swings with the cam axis stopped at chain reverse travel eliminates the necessity for a clutch mechanism for disconnecting the interlocking between the cam shaft and the plunger of the pump unit at chain reverse travel, resulting in the reduced weight and the simplified construction of the lubricating apparatus that eventually leads to lowered manufacturing cost.
  • the installation position of the checker arm relative to the cam shaft can be altered with ease.
  • the lubricating apparatus can be applied to chains traveling at a variety of angles with the installation position of the lubricating apparatus being held horizontal.
  • This novel constitution makes it unnecessary to change the installation of bleeder pipes that are provided for oil-bus lubricating parts in the apparatus, thereby facilitating the job of installing the lubricating apparatus.
  • the checker arm engagement position can be easily adjusted so that the checker arm is engaged at a proper position in the width direction of the chain according to the size thereof.
